Based upon the technology of the Coronus Grav-carrier, the smaller Caladius grav-tank is designed to utilise the firepower afforded by the heaviest elements of the Legio Custodes’ arsenal on a highly mobile, protected platform. Given the fusion of advanced systems and weapons, the Caladius is perhaps the most powerful battleline armoured unit of its size in the Imperium’s forces, utilising technologies and materials derived not only from the Dark Age of Technology, but from developments made as a result of the Great Crusade’s two centuries of warfare.

Featuring the same silhouette as the other Caladius Grav-tank variants, but with an especially aggressive-looking turret profile featuring the above-mentioned Arachnus blaze cannon, the Annihilator is appropriately named. Covered in extra detailing such as the cooling flasks that dissipate the immense energies unleashed whenever this tank attacks, photonic accelerators, visible engine and two lastrum bolt cannon on the front of the hull.
